IMPROVEMENT IN EXTENSION WAGON-BODIES.

Specification forming part of Letters Patent No. 177,142, dated May 9,1876; application filed Septembtr 20, 1875.

To all whom 'it may concern:

Be it known that I, JOSEPH K. MILNOR, of the city of Baltimore and Stateof Maryland, have invented certain new and useful Improvements inWagons, of which the following is a specification and I do herebydeclare that in the same is contained a full, clear, and exactdescription of my said invention, reference being had to theaccompanying drawing, and to the letters ofreference marked thereon.

My invention relates to a wagon lthe body of which is constructed insuch manner as to admit of its being extended longitudinally, as and forpurposes hereinafter described.

In the description of my invention which follows, due reference must behad to the accompanying drawing, forming a part of this specitication,and in whichv Figure lis a side view of my improvedwagon, and Fig. 2 aplan of the same.

Similar letters of reference represent similar parts in both figures.

A is the outer body of the wagon, connected to the front wheels andrunning-gear; and B, the inner body, attached to the rear Wheels,

and adapted to slide within the outer body A.-

rlhe inner body B is tted with rollers a, which serve to lessen thefriction of the moving parts in the longitudinal extension of the Wagon.The relative positions of the inner and outer bodies, which regulate thelength of the wagon, are maintained by means of a slot, b, in the outerbody A, and a bolt, c, which is secured to the inner body B, and passesthrough the said slot, with a thumbnut, el, on its outer end.

The advantages I claim for wagons constructed lin accordance with theimprovements herein described consist, chieliy, in their adaptation togreat variation in load and economy of space, in view of theircapaci-ty.

Having'thus described my invention, what I claim as new, and desire tosecure by Letters Patent ofthe United States, is-

l. aIn combination with the bodies A and B, the friction rollers a,substantially as described.

2. The slotted outer body A, combined with the inner body B and clampingdevices c and d, substantially as and for the purpose specified.

In testimony whereof I have hereunto subscribed my name this 9th day ofSeptember, in the year of our Lord 1875.

JOSEPH K. MILNOR.
